Flanker Derbyshire is well travelled throughout Italy having played for Cavalieri, Gran Parma, Petrarca and his current side Treviso. Derbyshire also had a brief stint at Stade Francais but failed to make an impact. He made his debut against Australia for the national side in June 2009 and will go to the forthcoming World Cup having been named in Nick Mallett's 30-man squad.
